UNITED STATES PATENT E. W. ARNOLD, OF BOSTON, MASSACHUSETTS.

MODE 0F REGULATING THE `TEMPYERATURE OF INKING-ROLLERS AND INKy USED THEREWITH IN THE INKING APPARATUS 0F PRINTING-PRESSES.

Specification of Letters Patent No. 394, dated September 211', 1837.-

To all whom it may concern.'

Be it known that I, ELIPHAZ VVns'roN ARNOLD, of Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented, made, and applied to use a new and useful Invention for Regulating the Temperature of Inking-Rollers and Ink Used Therewith for PrintingPresses in the Operation of Printing, which I specify as follows, namely:

The drawing hereto annexed and marked X is to be taken and considered as a part of this specification.

C represents a hollow metallic drum to be made of copper or other metal, of the usual size of inking drums now used for printing presses which drum is to receive the ink from a common distributing roller like those now in use that take it from the ink fountain underneath andv from which drum the ink is to be taken in the usual way by inking rollers for inking the form like those now in use. The surface of this hollow metallic drum should be perfectly smooth and the thinness of the metal from the interior to the exterior surface or periphery shall be such, having regard always to the strength of the drum, that hot or cold water when let into the hollow space in the drum may most readily have effect upon the temperature of the ink on the external surface and the inking rollers for inking the form when they shall be brought upon it by the transmission of heat and cold. Both ends of this hollow metallic drum or cylinder are to be solid with journals at each end to supportit, and a shaft at one end to which the power which is to move and turn it is to be applied in the usual way. The journal at the end opposite to that to which the power is to be applied is to be made hollow, so that cold or hot water by means of a tube may be introduced into the hollow metallic drum and discharged therefrom as hereinafter mentioned.

A represents a. reservoir about a foot more or less above the upper surface of the drum from which the hot or cold water is to be taken.

B represents a tube of a size suitable to be introduced at E into the hollow aperture in the journal of the hollow metallic drum so as to conduct the water from the reservoir into the hollow metallic drum. The tube is adjusted to the end of the journal and to be so bent upward that the end within the hollow metallic cylinder shall reach Very nearly to the upper interior surface of the hollow metallic cylinder at the top leaving only room suiiicient for the water to pass out freely when it rises to the top or end of the pipe within the hollow metallic cylincler. The other end of this pipe which is without the hollow metallic cylinderis to be bent upward so that the end may be six inches more or less above the topvof the hollow metallic cylinder and below the reservoir and is to vhave a stop cock at the end Gr by which the water can be let off as occasion. may require. This pipe is to be fixed and soldered into the tube at N so that the water may not pass out from the metallic cylinder Y between it and the tube. The tube is held frame. When the hot or cold water is brought into the reservoir A as occasion may require for heating or cooling the ink and inking rollers it passes down the tube B and into the hollow metallic cylinder at F by passing between the pipe D D and the interior surface of the tube B and lills the hollow metallic cylinder, and when the stop cock at G is turned so as to let it oftl it passes through the pipe D D and passes oif at G until the water in the reservoir is reduced to the level with the top of the pipe at G. By this means the water may be changed in the hollow metallic cylinder, and by turning the ends of the pipe downward so that it may act as a siphon the water may be wholly drawn from the hollow metallic cylinder as occasion may require. The'object of the said invention is to keep the inking rollersA and ink as far as may be of a proper tem-' perature for working'in hot or cold weather in any climate and to prevent the rollers from melting and the ink from filling up the types in warm weather and to prevent the upright and fast in a box screwed to the n inking rollers from becoming too hard and the ink from becoming too stiff in Cold Weather.

What I claim as new and of my invention 1s- Y The heating and cooling and regulating of the temperature of inking rollers and ink in the operation and process of printing by the means aforesaid.

In Witness that the above is a true speoiti- 10 i cation of my invention have hereto set my hand this sixteenth clay June in the year of our Lord one thousand eight hundred thirty seven.
